Application filed January 19, 1924, Serial No.

This invention relates to an apparatus for working paper. card, orother like ma terials. 1

It comprises a machine for working the material and a feeding mechanismprovid ed with an automatic feed table. this feed table being subject to the action of. a mechanism which allows it to be moved into a. raised position, so as to provide a free space to allow of passing between the machine for working the material and the feed.

The accompanying drawing illustrates the invention in one construction, given by way of example. I

Fig. 1 is an elevation. (of the sidev opposite to the control) showing in part a feed apparatus and a shaping machine; the automatic feed table is in operation and the hand feeding table is in the lowered position.

Fig. 2 is a sectional elevation of the feed and of the shaping machine, the automatic feed table being raised, or out of operation, and the table for hand feeding being in the operating position.

Fig. 3 is a plan view (of the control side) showing the hand feeding table raised, the feed control, the part above the line a, a of Fig. 2 being'omitted for the sake of clearness.

Fig. 4 is a plan view (of the side opposite the control) showing the automatic feed table and the hand feed table lowered, the locking mechanism and the means for raisinn the automatic feed table.

Fig. 5 illustrates the mounting of the feed as seen from the side where the pile of paper stands. Y I

Figs. 6 and 7 illustrate details of this mounting in different positions.

Fig. 8 is a section on the line b of Fig. 5 of the mounting in the position of rest.

The assembly illustrated in Fig. 1 shows at the right hand side the automatic feed. apparatus A with an automaticfeed table 1 and at the left hand side the shaping machine 13 with a hand feeding table 2.

The automatic feed table 1 (Fig. 1) receives the sheets taken by the layer-on from the pile of paper 3. Its purpose is to transportt-he sheets andto place them in correct position before they are taken by the shapingmachine. The means for separating the sheets and for putting them in position 682,397, and. in Switzerland January 26. 1923.

are not illustrated, but only the belts 4 which serve to transport the sheets and the roller 5 which drives the belts are indicated in Figs. 1, 2 and 4. The supports 6 of the automatic feed table are connected together by ties 8 and 9 at one end and at the other by the roller 5. They pivot about the principal shaft 10 which is carried by the members l1 and 12 of the feed frame. The automatic feed table is connected tothe shaping machine by bolts 13 and 14, which are fixed upon a shaft 15 adapted to turn in the members-16 and 17 of the frame of'the shap-- ing machine. The lever 18 pinned in the shaft 15 allows the bolts to be operated.

Two toothed sectors 19 mounted on the supports 6 engage with teeth 21' formed in a shaft 23 adapted to turn in the members 1.1 and 12. of the feed frame. A. wheel 24 keyed on the shaft-23 is driven by a pinion 25 rigid with a crank 26 capable of turning freely on a stub shaft 27 (Fig. 4). a pawl 28 preventing its rotation in one direction. A pulley 29, bymeans of gearing 30, 31 and 32 operates the shaping machine and a bevel gear 33, 34, 35 and 36 operates a con trol pinion 37 of the feed apparatus. The pinion 37 turns idly on the shaft 38 rigidly mounted on the member 12 of the feed frame and drives a wheel. 39 mounted idly on the principal shaft 10 of the feed, as also a gear 40, through a gear 41 and shaft 42. In the lowered position of the automatic feed table 1, a gear 43 mounted on the end of the roller 5 engages with the gear 40, thus aotuating the roller 5 and the belts 4 (Fig. 2). The shaft 10' of the feed carries cams and gears which operate the various parts, that are not illustrated, of the feed andflof the automatic. feed table. The shaft 10 is driven'by the gear 39 (Fig. by means of a clutch which is engaged or disengaged by means of a lever 44, which is keyed on one end of a shaft 45 adapted to rotate in the members 1.1 and 12 of the frame and carrying at its other end a cam 46. When the clutch is engaged, the lever 44 is moved into the position 44 (Fig. 1) and this causes the cam 46 to act on a roller 47 of a lever 48. The lower end 49 0f the lever 48 is crescentshaped, and takes the position indicated at 50 in Fig. 8. A roller 51 mounted on the sleeve 52 0f the clutch is then freed by the crescent shaped end 49. Under the action the hand feeding table 2 (Fig. 1).

of a spring 53 the clutch sleeve slides lengthwise of the shaft 10 and the feather- 54 until the slot 55 engages with the tooth 56 of the wheel 39, which causes the rotation of the shaft 10. To disengage the clutch, the lever 44 is moved into the position indicated in Fig. 1, the crescent end 49 under the action of the spring 57 takes up the position illustrated in Fig. 7. The roller 51 in the course of its rotation rises on the inclined plane 58 (Fig. 5) of the crescent end and produces the disengagement of the parts 55 and 56. Upon disengagement of the clutch, a roller 59 (Fig. 7 mounted on a double lever 60 pivoted upon the lever 48 comes in contact with a crown 61, under the action of a spring 62. At the precise moment when the clutch parts disengage, the roller 59 is opposite to a slot 63 in the crown 61. The tension of the spring 62 causes the roller 59 to moveto the bottom of the slot 63, which produces a supplementary rotation of the crown 61 and of the shaft 10, the crown being rigidly mounted upon'the latter by means of the key 54. The effect of this rotation is to increase the separation of the clutch parts 55 and 56, the roller 51 of the clutch sleeve continuing for this reason to travel on the inclined plane 58. The stopping position is' illustrated in Fig. 6. At this moment the roller 59 has reached the bottom of the slot 63 and thus holds the shaft 10 in a predetermined position, whatever the speed of rotation of the wheel On engagement, the lever 60 which carries the roller 59 strikes against a pin 64 which causes the roller 59 to move out of the slot 63 before the crescent end 49 allowsthe roll or 51 to escape from the clutch sleeve 6 and 8).

The arms 65 and 66, pinned upon a shaft 67 adapted to turn in the members 16 and 17 of the shaping machine framesupport The arms 65 and 66 are provided'with slots 68 into which enter the bolts 70 and 71 forkeeping the table 2 in the hand feeding position (Fig. 2).

The bolts 70 and 71 pinned on the shaft 15 are operated by the lever 18.

The operation of the automatic table is as follows:

When the lever 18 is operated, bolts 13 and 14 release the supports of the automatic feed table 1, which turns about the shaft 10 upon the crank 26 being turned. The space obtained between the feed table 1 and the shaping machine B allows an operator to pass between the two machines.

If hand feeding is to be carried on. the table 2 is raised into the place of the automat-i0 feeding table (Fig. 2) and is kept in position by the bolts 70, 71 operated by means of the lever 18. The sheets taken from the pile 3 are freed from the roller 5 by the turning of the automatic feed table, and are put in position by hand before being taken by the shaping machine.

The turning of the automatic feed table 1,

accordin to Fi 2 sto as the rotation of the roller owing to the fact that the gear 43 becomes disengaged. from the gear wheel 40. The operation of the parts of the feed and of the automatic feed table is stopped when the rotation of the shaft 10 is stopped by placing the disengaging lever 44 in the lower position which allows the shaping machine to operate alone, the wheel 39 then turning idly on the shaft 10 and the gear 43 being out of engagement with the wheel 40. WVhen the automatic feed table is lowered and is held by the bolts 13 and 14, only the shaping machine and the transporting belts 4 can be operated, the lever 44 in its lower position stopping the parts of the feed and of the automatic feed table.

lVhen the lever 44 is raised into the position 44 and is then lowered, one or more sheets can be passed through the shaping machine at predetermined intervals without stopping the machine. Since a revolution of the shaft 10 causes the movement of the feed parts required for displacing one sheet, one sheet will pass into the shaping machine or other paper working machine at each revolution of this shaft.

On disengagement of the roller 59 entering the slot 63 causes a supplementary separation of the clutch parts 55 and 56 and s ops the shaft 10 always exactly in the same position whatever may be the speed of rotation of the wheel 39.

Instead of being pivoted upon the paper working machine, the hand feeding table 2 may be similarly mounted upon the feeding machine.
